This attack, raising a lot of questions, once again, about the safety of these so-called backyard zoos. Abc's rob nelson is here with more. Reporter: Good morning. Good morning, everyone. Some terrifying moments for a, woer at a zoo in oklahoma. The victim of a violent attack that is yet another reminder of the danger of working with wild animals. This morning, we're getting a closer look at the zoo in oklahoma where a female worker was brutally attacked by a male tiger early saturday morning. The incident happened here at the gerald wayne zoo and park in oklahoma. According to a spokesperson, the tiger bit the woman's hand, pulling her into the cage through le just four ihes wide. Despite initial fears the worker would lose her arm, surgeons were able to save it. She's doing well. But admits the attack is her fault. Every once in a while, people let their guard down, working with animals like this. And they forget that they're animals. Reporter: He says this is the first incident of its kind to happen at this small zoo in rural oklahoma, where he also lives and performs. But this is hardly the first time we've heard of animal attacks with these so-called roadside zoos. In 2005, 17-year-old haley hildebrand died from injuries she sustained while posing with a tiger at the lost creek animal sanctuary in kansas. The tiger lunged at her attacked her and got her by the back of t neck. Reporter: Jack hanna says not everyone is equipped to tame the wild animals. I've seen this for 45 years. When you're dealing with a wild animal, you have to be careful with what you do. Reporter: The park says this tiger wl not be put down. Although, the animal has been quarantined and will not be returning to the public exhibit anytime soon. Now, at the time of the incident, the victim, who has not been identified, was wearing a goose down and leather jacket. The jacket may have gotten stuck in that cage. Or the tiger attracted to its smell. Even though the zoo blames the employee for what happened, the incident remains under investigation. Meanwhile, though, the humane society of the u.S. Called the zoo substandard. And says it has a history of animal attacks. Calling it, quote, guys, a ticking time bomb. The humane society is worked up about these zoos. Thank you.
